I can not believe you thought this place was good. Read my review from last Memorial Day. Or the review two newer than yours.
I had nothing good to say about the hotel. It was disgusting, unsafe, impossible to secure, the service was the worst. I hear it has bed bugs but I did not experience any. I think we got lucky to get out of there without getting bedbugs or worse.
